[0002] Laminate is a type of laminated product. Laminate is a whole formed by stacking and hot-pressing two or more layers of resin-impregnated fibers or fabrics. Laminate can be processed into various insulating and structural parts and are widely used in motors, transformers, high and low voltage electrical appliances, electrical instruments and electronic equipment. Laminate can be in the form of plates, tubes, rods or other shapes. Laminates need to be cut before they are put into use, and a laminate cutting device is required.

Finally, the small motor 32 is started so that the rapidly rotating grinding sheet 33 can fully deburr the cutting surface of the laminate.

[0039] The deburring part 28 includes a connecting seat 29, a hydraulic cylinder 30, a positioning slider 31, a small motor 32 and a grinding sheet 33.
